UUX2A220MNL6GS

The UUX2A220MNL6GS is a surface-mount aluminum electrolytic capacitor from Nichicon’s UUX series, a chip-type design optimized for wide temperature operation. It delivers a 22 µF capacitance at a 100 V rated voltage with a compact φ8 × 10 mm can and embossed carrier taping for automated assembly.

Designed for demanding environments, this AEC-Q200-rated device combines high-voltage capability, a wide operating temperature range and specified endurance to support automotive and other temperature-critical applications where reliable power filtering and decoupling are required.

Key Features

• Electrical performance — 22 µF nominal capacitance with ±20% tolerance at 120 Hz, 20°C, and a rated voltage of 100 V.
• Loss and leakage — Low dissipation with tanδ = 0.08 (measured at 20°C, 120 Hz) and leakage current specified as 66 µA for this part.
• Ripple current capability — Specified ripple performance of 121 mA at 120 Hz (low frequency) and 202.1 mA at 10 kHz (high frequency) for power-decoupling uses across frequency ranges.
• Wide temperature and endurance — Operating range −55°C to +105°C with a rated endurance of 2000 hours at 105°C; suitable for long-term elevated-temperature operation per the UUX series endurance specification.
• Automotive-grade qualification — AEC-Q200 rating included in the product specifications for applications requiring industry-recognized reliability standards.
• Package and assembly — Surface-mount radial can (φ8 × 10L) with a recommended land pattern of 8.3 × 8.3 mm and supplied in embossed carrier taping for pick-and-place automation.
• Soldering robustness — Series-level resistance to soldering heat is specified in the datasheet (hot plate exposure at 250°C for 30 seconds) with defined limits on capacitance, tanδ and leakage after exposure.

Typical Applications

• Automotive power electronics — AEC-Q200 rating, 100 V rating and wide temperature range make this capacitor suitable for power filtering and bulk energy storage in vehicle electronic modules.
• DC–DC converters and power modules — 100 V rating combined with specified ripple currents at 120 Hz and 10 kHz supports smoothing and decoupling in high-voltage converter stages.
• Engine control and ECU systems — Long endurance at 105°C and robust leakage/tanδ characteristics provide stability for control electronics operating across automotive temperature extremes.

Unique Advantages

• High-voltage capability: 100 V rated voltage enables use in higher-voltage rails without needing alternate part types.
• Wide operating temperature: −55°C to +105°C supports deployments across harsh thermal environments common in automotive and industrial systems.
• Automotive qualification: AEC-Q200 rating gives a documented reliability foundation for vehicle-grade designs.
• Balanced ripple performance: Specified ripple currents at both low and high frequencies (121 mA at 120 Hz; 202.1 mA at 10 kHz) support a variety of power-conditioning roles.
• Assembly-ready packaging: Embossed carrier taping and compact φ8 × 10L SMD can simplify automated placement and board integration.
• Endurance at elevated temperature: 2000 hours at 105°C specified life supports longer-term stability under sustained thermal stress.
